GASOLENE-VALVE.

Specification of Letters Patent.

Application filed December 13, 1320.y Serial No. 430,570.

To all whom t may concern.'

Be it known that I, GORDON C. BREDIN, a subject of the King of GreatBritain, residing at Galt, in the county of lWaterloo and Province ofOntario, Canada, have invented certain new and useful Improvements inGasolene-Valves, of which the following is a specification.

My invention relates to improvements in valves and more particularly toimprovements in valve controlled devices for retaining a reserve fuelsupply inthe regular tank of a motorr vehicle, and consists essentiallyof a hollow tube extending from the top of the tank to within a closedistance of the bottom and having a port a short distance from the lowerend, together with means for closing the port.

The primary object of the present invention is to providea device toserve as a warning when the fuel supply has become low, by temporarilychecking the fuel feed.

A further object is to provide an article 'of the class specified whichmay be set to retain a predetermined amount of fuel in the supply tankto be used in an emergency such as unexpectedly running low on thesupply in order to overcome the liability of exhausting the fuel supplywhile distant from a source of supply. n

`A still further object is to provide such a device which will besimple, durable, eicient and comparatively inexpensive to manufacture.

These, together with other objects, may be attained by the construction,combination and arrangement of the parts as will be hereinafter morefully described, illustrated in the accompanying drawing, and pointedout in the claim hereunto appended.

Reference being had to the drawing:

Figure 1 is an elevation of the invention;

Fig. 2 is a cross-sectional elevation taken on the line II--II in Fig.1;

Fig. 3 is a top View ofthe device;

Fig. 4 is a cross-sectional top view taken on the line IV-IV in Fig. 2;

Fig. 5 is a cross-sectional top view taken on the line V-V in Fig. 1;

Fig. 3v is a cross-sectional top view taken on the line Vl-VI in Fig. 2;and,

Fig; 7 is a similar view to Fig. 6 showing'` the valve open.

Similar reference characters refer to sim-y ilar parts throughout theseveral views.

ln the drawing A indicates the top of the fuel tank which is providedwith a threaded` bushing 2 into which is threaded the head B.

by means of theV heXagon portion 3 thereonf: A perpendicularly,disposedltube is at-y tached to the lower end part of thefsaid Patented Dec. 6,1921.

head and extends to within a close distance of the bottom of the tank A.rThe gasolene is sucked or pumped through the tube C by such means asare well known such as the vacuum system, through the feed pipe'orgasolene line a which is connected to a bushing 5 around a neck portion6 of said head, where the said feed pipe communicates with the core 7 ofthe head, with which the tube C communicates.

A turn plate D has a neck D journaled in the upper part of the core 7 inthe head B and has a concentric recess into which fits the stem E. Thestem is rotatable in a portion of the core 7 of the correspondingdiameter and is secured against relative rotation with the turn plate Dby the taper pin 8. A ring 9 having vcorresponding diameter to the upperpart of the core 7 and fitting tightly around the stem E, tensionallyretains packing 10 in tight relation to the said stemV by means of thespiral spring' ring enables it to be compressed and consequently to beconstantly tensionally engaged with the walls of thel tube C, and whenturned by the stem E to seal the port 13.

The operation of the device is as follows:

When the car is in operation, the port 13, which is located in the tubeC at a suitable distance from the bottom of the tank'at a point, say, ona plane with the level of a gallon of fuel, is normally open and notclosed by the ring F, which position. is governed by the positionof theturn plate D.

At such turn the word tank or other suitable indication is registeredwithv the arrow on the hexagon 3.- This position is shown in Figs. 1, 3and 7.

`The fuel is drawn through the end of the tube and through the port 13,but when the fuel level has become lower than the port, air is admitted,and being lighter than the fuel, is sucked through consequently stoppingthe motor as a warning to replenish the `fuel supply. The operator mustaccordingly give a half turn to the turn plate D which closes the port13 and permits the remaining amount of fuel to be drawn through the endof the tube C. At this time the arrow adjacent the word, reserve forexample, is registered with the arrow on the h eXagon 3. This positionof the valve is shown in Fig. 6.

` A pin 14 is provided the stem E which engages the stop 15 to properlylimit the rotary motion thereof;

Having now fully described my invention, what I claim and desire tosecure by Letters Patent is 1n a device of the class described, thecombination with a fuelltanl, of a tube extending into the depth of thetank and communicating above the tank with a fuel feed pipe, said tubehaving an opening at its lower end for reception of fuel andhaving aport at a distance above the opening, a resilient radially eXpandiblesplit ring formed of a portion of tubing having alongitudinal sectionremoved, rotatable within `said tube,

adapted to seal said port therein and to open 1t by rotation of the ringto a 4point where the split therein registers with said port,

and means for rotating said ring from without the tank.

In testimony whereof I have aflixed my signature.

- GORDON C. BREDIN.
